Manage air conditioning and pressurization through the shared hydraulics-and-air panel. The air system provides pack, isolation-selector, recirculation-fan and trim-air positions plus cabin conditions. Use the installed detent decoding for OFF, AUTO and OPEN. Cabin differential pressure is not starter duct pressure, and current cabin altitude is not the LAND ALT target.
